			<li>The index.php serves as the front controller, initializing
				the base resources needed to run CodeIgniter.</li>
			<li>The Router examines the HTTP request to determine what
				should be done with it.</li>
			<li>If a cache file exists, it is sent directly to the browser,
				bypassing the normal system execution.</li>
			<li>Security. Before the application controller is loaded, the
				HTTP request and any user submitted data is filtered for security.</li>
			<li>The Controller loads the model, core libraries, helpers, and
				any other resources needed to process the specific request.</li>
			<li>The finalized View is rendered then sent to the web browser
				to be seen. If caching is enabled, the view is cached first so that
				on subsequent requests it can be served.</li>
